三维CT血管成像技术在椎动脉型颈椎病诊断中的应用

Application of Three-dimensional Computed Tomography Angiography in the Diagnosis of Cervical Spondylosis with Vertebral Artery Involvement

目的探讨三维CT血管成像技术在椎动脉型颈椎病诊断中的应用效果。方法选取我院神经外科2014年1月至2015年7月收治的45例椎动脉型颈椎病患者作为研究组,另选取42例同期健康志愿者作为对照组。对所有受试对象均行三维CT血管成像技术检查,比较2组检查结果。结果研究组3例椎动脉正常,8例单侧管腔变细,2例走行异常,3例血管硬化,8例管腔局限性狭窄,3例左侧受压,4例右侧受压,5例血管走行迂曲。对照组2例椎动脉变细。2组椎动脉直径中的右横径、右矢径、左横径、左矢径、左三维直径,横突内径中的右横径、右矢径、左横径指标差异均有统计学意义(P<0.05)。结论三维CT血管成像技术诊断椎动脉型颈椎病图像清晰,且对椎动脉直径和横突内径测量准确,应用效果显著。

Objective To explore the use of three-dimensional computed tomography angiography （3D CTA） in the diagnosis of cervi- cal spondylosis with vertebral artery involvement. Methods The study group included 45 patients treated for cervical spondylosis with vertebral artery involvement, from January 2014 to July 2015;42 healthy volunteers were selected as the control group. 3D CTA data of all research subjects were evaluated. Results The findings in the experimental group included 3 patients with normal vertebral artery, 8 with unilateral narrowed lumen, 2 with aberrant route, 3 with vascular sclerosis, 8 with local lumen stenosis, 3 with left side compression, 4 with right side compression, and 5 with vessel tortuosity. The right vertebral artery transverse diameter and radius, the left vertebral artery transverse diameter and radius, and 3D images of the left vertebral artery diameter, right transverse diameter, right radius, and left trans- verse process inner diameter showed statistically significant differences between the two groups （P 〈 0.05）. Conclusion 3D CTA can be used for accurate diagnosis of cervical spondylosis with vertebral artery involvement and can clearly display the diameter of the vertebral artery and the transverse diameter of the vertebral artery.
